The crocodilian caudal vertebra is obtained from the Tsubusagawa Formation. Its size is same and its gross shape is resemblance to the 20th caudal vertebra of Crocodylus porosus, NTM R16036, total length for 513 cm. However, in comparison with NTM R16036, the direction of neural spine is more dorsocaudal, and the M. longissimus caudae and M. semispinalis caudae might be more developed in the Tsubusagawa specimen. With respects to the hitherto regarding crocodilian fauna, the Tsubusagawa specimen is identified to the crocodyline crocodylid, Toyotamaphimeia machikanensis. The caudal vertebrae are preserved only three, 1st to 3rd , in the type specimen of T. machikanense, and thus direct comparison with the Tsubusagawa specimen is impossible. According to Chinese classic dictionary by Lu (1174, the 12th Century), the tail of crocodile which may be identified as T. machikanensis is prehensile as if elephant trunk. The posterior condyle of this vertebra is well developed, and thus there is some possibility to support the evidence of prehensile tail. At the early Miocene, T. machikanensis might be derived from crocodyline crocodylid Maomingosuchus petrolicus. T. machikanensis is differ from Maomingosuchus petrolicus in having the largest 7th maxillary teeth and much larger body. The large canini-form development of 7th maxillary teeth is an adaptation for the relatively larger prey. As a larger prey, the presence of oxygasterine cyprinid Hypophthalmichthys (Silver Asian Carp), total length for 1 metre or more, is seemed to be involved with the secondary caniniform development of 7th maxillary teeth and gigantism of Toyotamaphimeia. The oldest fossil record of Toyotamaphimeia is the early Miocene and that of Hypophthalmichthys is too. Hypophthalmichthys is famous for its frequently jumping when disturbed. Although this jumping is hitherto claimed as enigmatic, it could be interpreted as anti-predatory behavior against Toyotamaphimeia.

Psyllids (Hemiptera: Sternorrhyncha: Psylloidea) are plant sap-sucking insects that include important agricultural pests. To obtain insights into the ecological and evolutionary behaviors of microbes, including plant pathogens, in Psylloidea, high-resolution analyses of the microbiomes of nine psyllid species belonging to the family Triozidae were performed using high-throughput amplicon sequencing of the 16S rRNA gene. Analyses identified various bacterial populations, showing that all nine psyllids have at least one secondary symbiont, along with the primary symbiont “Candidatus Carsonella ruddii” (Gammaproteobacteria: Oceanospirillales: Halomonadaceae). The majority of the secondary symbionts were gammaproteobacteria, particularly those of the order Enterobacterales, which included Arsenophonus and Serratia symbiotica, a bacterium formerly recognized only as a secondary symbiont of aphids (Hemiptera: Sternorrhyncha: Aphidoidea). The non-Enterobacterales gammaproteobacteria identified in the present study were Diplorickettsia (Diplorickettsiales: Diplorickettsiaceae), a potential human pathogen, and Carnimonas (Oceanospirillales: Halomonadaceae), a lineage detected for the first time in Psylloidea. Regarding alphaproteobacteria, the potential plant pathogen “Ca. Liberibacter europaeus” (Rhizobiales: Rhizobiaceae) was detected for the first time in Epitrioza yasumatsui, which feeds on the Japanese silverberry Elaeagnus umbellata (Elaeagnaceae), an aggressive invasive plant in the United States and Europe. Besides the detection of Wolbachia (Rickettsiales: Anaplasmataceae) of supergroup B in three psyllid species, a lineage belonging to supergroup O was identified for the first time in Psylloidea. These results suggest the rampant transfer of bacterial symbionts among animals and plants, thereby providing deeper insights into the evolution of interkingdom interactions among multicellular organisms and bacteria, which will facilitate the control of pest psyllids.
